This might very well be a three, four, or five-star book for many readers. For me it was entirely too basic and shallow in its research and analysis, though its goal of providing a small, short, focused snapshot of unions and such was probably met? Not entirely sure there, to be honest. I have read too much theory, history, economics and the like for this to be anything but a limp rehash of some serious topics. Unions are extremely polarizing for many people whether part of a union or not. Much of the "good parts" of capitalist work have been acquired via union efforts - something many workers are quite unaware of - but unions are also heavily bureaucratic and overly prone to graft, corruption, and favoritism, all things the union, in theory, is supposed to be against in principle. I am firmly anti-capitalist. The union is merely a method to make capitalism less awful, but that is like saying if I only punch you twice it is somehow better than if I had punched you three times. While objectively receiving two punches is "better" than three, neither scenario is desirable, right? Unions pull that third punch for management, who would just as soon punch you many more times. Why? Because they can. Capitalism works that way, and always will. Unions, while acquiring gains in their infancy, have done little to benefit the larger capitalist workforce in recent decades. Why? Because capitalism cannot succeed and flourish with strong worker rights and strong worker protections and better wages and more benefits and work-life balance. That would be communism. Not the communism most ignorant people think of - a la Russia under Stalin or China under Mao, the latter of which was slightly more communist than the former, strictly speaking, based on the incorrect definition of communism - but actual communism. Where the workers and management are equals in every way. There is no meaningful reason why the CEO makes more than the janitor (please don't argue skill value, as that argument withers when one thinks of garbage collectors, for example...), besides the fact that the CEO has power and wealth and can just replace the janitor whenever they feel like it, like if that janitor decided to ask for better working conditions, via a union (sub par choice, but not awful) or by revolutionary action that overthrows the capitalist order and replaces it with actual communism (ideal choice, though much more demanding).
Anyway. I would define this book as adequate, but at only the most basic level. Anyone who truly wants to be a troublemaker needs to embrace anti-capitalism with all their power. Unless we replace capitalism humans will cease to exist as a species. Capitalism is destroying the planet for human life, and any ridiculous notion that its tech will get us to Mars soon enough to belay that is not only laughable, it is patently ridiculous, since the problem isn't the planet we are on, it's the humans controlling what we do on it the planet that is the problem we must solve. And fast. Joining a union is not something I see as a step in the right direction, more like appeasement. And that is never a good thing when wholesale revolution is needed. Ask Neville Chamberlain about that...
